Years ago, before I knew better I decided to wash the running rigging in the washing machine. Not having the sage advice given above I just dumped them in, put in the soap and let her rip. No mesh bags, no tightly coiled line to interfere with the washing action.
Result: a very clean, multi-colored rat's nest that took hours to untangle.
BR--been there, done that. the mesh bags work great and serve to protect the lines from the little bit of abrasion that may occur. dawg-- as stated above by someone else, if your running rigging isn't up to a regular washer cycle, it's way past time to replace it.
as for problems with the admiral, i only do the lines when she isn't home. But she can always tell because the garage smells like Downey from the drying coils.
